Introduction
This is a culmination of mapping projects that have been completed throughout the VIS 2128 course. In this document you will find maps that demonstrate different r-studio skills that visually represent data.
The following skills will be demonstrated in this portfolio.
- Displaying multiple vector layers on the same map
- Calculating and displaying relationships among point and polygon layers based on distance
- Aggregating point data to a layer of polygons
- Calculating and displaying accessibility, based on travel time
- Converting between raster layers and vector layers
- Displaying raster data on a map
- Georeferencing a raster image
- Displaying data on an interactive map
Interactive Map
This interactive map of Tampa shows the male population spread across the city of Tampa. This map demonstrates the following skills:
- Displaying data on an interactive map
Georeferenced Map
The following map demonstrates a raster image that was georeferenced using Arc GIS. This map demonstrates the following skills:
- Georeferencing a raster image
Distribution and Distance Maps
Let’s take a look at maps based on the city of Boston!
Boston Landmarks Distribution
In this map I aggregated landmark point data into a Boston neighborhood polygon layer to show the distributions of landmarks throughout neighborhoods within the city. This map demonstrates the following skills:
- Aggregating point data to a layer of polygons
Boston Landmarks Distance to Parking
If you are visiting a landmark, you might want to park near it. In this map we look at the relationship of landmarks to city parking. This map demonstrates the following skills:
- Calculating and displaying relationships among point and polygon layers based on distance
Time and Travel Relationship Maps
The following maps demonstrate the relationship of interacting with points in the city based upon time and distance. Each maps demonstrates a different way of seeingt this relationship.
Isochrones
This map shows Isochrones based on transit travel times to the nearest Boston cafe. It demonstrates the following skills:
- Displaying multiple vector layers on the same map
- Calculating and displaying accessibility, based on travel time
Time Travel Matrix
This map shows a Time Travel Matrix based on transit travel times to the nearest Boston cafe. It demonstrates the following skills:
- Displaying multiple vector layers on the same map
- Calculating and displaying accessibility, based on travel time
Accessibility
This contour map shows accessibility by evaluating the walking time to the nearest Boston transit stop. It demonstrates the following skills:
- Displaying multiple vector layers on the same map
- Calculating and displaying accessibility, based on travel time
- Displaying raster data on a map
